Mako Mining Reports Positive Resource Reconciliation
Mako Mining Corp. has announced positive results from the first 12 benches of the San Albino vein at its gold project in Nicaragua. Mining yielded 32,208 ounces of gold and 55,687 ounces of silver from 103,783 tonnes of diluted material, averaging 9.72 g/t Au and 16.69 g/t Ag. These results show a 10% positive grade reconciliation compared to the mineral resource estimate, a significant validation of the geological model. The company aims to capitalize on this data for further exploration.

VANCOUVER, BC, Jan. 11, 2022 /PRNewswire/ - Mako Mining Corp. (TSXV: MKO) (OTCQX: MAKOF) ("Mako" or the "Company") is pleased to report grade and tonnage results from mining the first 12 benches of the San Albino vein at its San Albino gold project ("San Albino") in northern Nicaragua. The mined benches consisted of twelve, six-meter benches between 616 and 550 meters above sea level and contained a total of 32,208 ounces Au and 55,687 ounces Ag within 103,783 tonnes of diluted vein material grading 9.72 g/t Au and 16.69 g/t Ag.
The diluted vein material mined at San Albino thus far has positively reconciled on both grade and ounces by

Sampling, Assaying, QA/QC and Grade Estimation
Diluted vein material was estimated using vertical channel samples. Vertical channel samples respecting the geology were collected on 5-meter sections at approximately 4-meter spacing using a gas-powered rock saw where the vein is competent, or a rock hammer where the rock is strongly fractured or brecciated. Special attention is applied to standardize the width and volume of material taken using the rock hammer or rock saw. The coordinates of the channel samples are surveyed using a total station surveying device. Historical dump material estimation used blast hole data in addition to vertical channel samples. Continuous 3-meter samples over the 6m bench were collected from the blast holes using a sample collection pan that traps all the blast hole material. The entire sample is then split using a Gilson splitter.
Samples for the first 3.5 benches were kept in a secured logging and storage facility until such time that they were delivered to the Managua facilities of Bureau Veritas, an independent assay lab, for sample preparation. Pulps were sent to the Bureau Veritas laboratory in Vancouver for analysis. Gold was analyzed by standard fire assay fusion, 30-gram aliquot, Atomic Absorption Spectrometry (AAS) finish. Samples returning over 10.0 g/t Au are analyzed utilizing standard fire assay-gravimetric method. The Company follows industry standards in its quality assurance and quality control ("QA/QC") procedures. Control samples consisting of duplicates, standards and blanks were inserted into the sample stream at a ratio of 1 control sample per every 3 to 4 samples. Analytical results of control samples confirmed reliability of the assay data.
Samples from benches 592 to 550 were sent directly to San Albino Mine's on-site laboratory for preparation and assay. Gold was analyzed by standard fire assay fusion, 30-gram aliquot, with an AAS finish. The Company's onsite lab follows industry standards in its quality assurance and quality control ("QA/QC") procedures. The QA/QC program includes the blind insertion of certified reference standards and assay blanks at a frequency of at least 1 per 20 normal samples as well as the submission of field duplicates. In addition, approximately
The grade of the diluted San Albino vein and historical dump material were estimated using the inverse distance squared method ("ID2") from 1-meter composite intervals respecting the geologic boundaries. Samples were capped prior to compositing at 100 g/t Au in the San Albino vein, 7.0 g/t Au in the San Albino footwall, 4 g/t Au in the San Albino hanging wall and 25 g/t Au in the dump material. Capping values were based on analysis of previous diamond drilling results which were used in the MDA Resource. The search ellipse for the dump material was limited to 4 m for gold assays >2.5 g/t Au. The diluted grade of the San Albino vein for the first four benches was estimated using 3-D models of surveyed vein boundaries and surveyed mined surfaces where the vein boundaries were clearly defined. Within the Porcelana zone (benches 580-550), where the vein boundaries are diffuse due to fault stacking of the veins, the un-diluted grade of the San Albino vein was estimated using 3-D models derived from the surveyed channel samples defining the hanging wall, footwall, and vein boundaries. The diluted grade of the vein was estimated using daily tonnage estimates of the mined material.
